FREDERICK PAUKERT, OF REGENT, NORTH DAKOTA.

GRAIN-SEPARATOR.

Specification of Letters Patent.

Application filed May 3, 1911.

Patented Jan. 2, 1912.

Serial No. 624,744.

To all whom it may concern:

Be it known that I, FREDERICK PAUKERT, a. citizen of the United States, residing at Regent, in thecounty of Hettinger and State of North Dakota, have invented certain new and useful Improvements in Grain-Separators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in grain separators and more particularly to a machine of this character for cleaning seeds by removing and separating foreign seeds and other substances therefrom.

The invention has for an object to provide a machine of this character which will possess advantages in points of efiiciency, durability, is inexpensive of manufacture and at the same time being simple in construction and operation. I

With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which Figure 1 is a side elevation; Fig. 2 is a top plan view; Fig. 3 is a vertical longitudinal sectional View; and Fig. 4 is a transverse sectional view.

Referring more particularly to the drawings 1 indicates the frame, preferably of the form here shown, but may be of any suitable construction, and the same supports an inclosing casing 2, at one end of which is formed a drum 3, in which is disposed a blower fan 4. The shaft 5 of the fan 4 is journaled in suitable bearings 6 in the frame 1 and the said shaft is connected by means of the belt 6 with a power wheel 7 operated by a handle 8 or other suitable means can be used, and a pulley 9 is keyed upon the other end of said shaft. A hopper 10 is mounted in the upper side of the easing. To regulate the flow of grain from the hopper into the body a plate 10 is provided adapted to slide on the guides 10 said plate having a rod a secured to the bolt 6 in the back side of the plate, and having its outer. end mounted on the crank arm 0 of the crank shaft d which is mounted in suitable bearings in the frame. A hand lever c is secured upon the outer end of said shaft, having a catch f formed thereon to engage in a notched rack g secured to the side of the frame. 7

An upper frame 11, which comprises the sides 12 and suitable end connections 13, is disposed below the hopper 10. The frame 11 is provided with a chaffing screen 14,

which is secured to the sides and ends thereof, and a bottom 15 is secured to the lower side of the frame, which is made into concave form as indicated at 16, near its outer end and the same is provided to throw the grain against the return board 17 secured to the end of the frame. The upper end of the frame 11 is provided with the lugs 18 upon each side thereof and adapted to slide in the grooved strips 19 secured to the sides of the casing. The lower end of the frame 11 is mounted upon the cam 20 by means of the pin 21, which is disposed through the roller 22 and has its lower end secured in one side of the cam 20. The roller 22 is mounted in a housing 23 formed in the lower end of the frame 11 and has its ends mounted in suitable bearings 24.

The cam 20 is keyed upon the upper end of a vertically disposed shaft 25 mounted in suitable bearings 26 in the cross beam 27.

Keyed to the lower end of the shaft 25 is I a cam 28, to which is secured the frame 29 by means of a pin 30 passing through the roller 31 mounted in the outer end of the frame and its upper end secured in one side of the cam 28. The roller 31 is mounted in i a housing 32 formed in the outer end of the frame 29 and having its ends mounted in suitable bearings 33.

The cams 20 and 28are operated by means of a bevel gear 34 mounted on the shaft 25 and disposed in a suitable housing 35 formed in the cross beam 27 and adapted to mesh with a bevel gear 36 mounted upon the inner end of the shaft 37, which is horizontally disposed in the cross beam 27, said shaft frame 29 is provided with a chafiing screen 45, and an inclined bottom 46 is secured to said frame, said bottom being provided with a central concave surface 47 adapted to bring the grain down to the bottom of the casing where it strikes the inclined return board 48 and is discharged through the opening 49 into a suitable chute 5O thence it is run off into bags or other suitable receptacles.

When the pulley 39 is rotated by the belt 40, which is connected to the power shaft, the cams and 28 are rotated by means of the bevel gears 34 and 36, thus it will be seen that the frames 11 and 29 will be moved longitudinally and transversely, and the rollers 22 and 31 serve to produce a universal movement between the cams 20 and 28 and the frames 11 and 29. Thus it will be obvious that when the material to be separated is thrown into the hopper 10 it will drop directly onto the screeny14 and the grain and chaff will drop through onto the bottom 15 and will be carried down and deposited on the screen 45 while the straw and larger material are discharged out of the front end of the casing. While the grain and chaff are falling from the screen 14 to the screen 45 the draft from the fan 4 will tend to blow the chaff and foreign seed out through the front end of the casing and the good grain will drop down on to the screen 45 and thence through onto the inclined bottom 46 where it is discharged into the opening 49.

The bottom 46 is to extend in so that when the inner end of the frame 29 is disposed in the casing to the limit of its movement the bottom will be brought up to the return board 48 and when the frame is the farthest out on its outward movement the inner end of the bottom 46 will come flush with the other side of the opening 49.

To regulate the flow of grain through the opening 49, I have provided a regulator 51 in the shape of a scoop which is adapted to catch any grain that is not discharged through the opening 49, said regulator being provided with a back side 52 and the two inwardly extending ends 56 and adapted to slide on the guides 57, said regulator having a rod 53 secured to an eye-bolt 54 in the back side of the regulator, and having its outer end mounted on the crank arm 55 of the crank shaft 58 which is mounted in the bearings 59 in the frame 1. A hand lever 60 is secured upon the outer end of said crank shaft, having a catch 61 formed thereon and adapted to engage in a notched rack 62 secured to the frame.

It will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying the invention into practice without sacrificing any of the novel features or departing from the scope thereof.

Having thus described the invention what is claimed is 1. In a device of the character described, the combination of a casing supported by a suitable frame, a drum formed at one end of said casing in which is disposed a blower fan, oppositely inclined frames carrying chafling screens mounted in said casing for longitudinal and transverse movement, a cross beam mounted in the front end of said casing and between the adjacent ends of said inclined screen frames, a vertically disposed shaft mounted in said cross beam, cam wheels keyed to each end of said shaft, said cams being connected to said frames, by means of pins disposed through rollers mounted'in the end of said frames and having their free ends secured in said cams at one side thereof, and means for imparting motion to said vertically disposed shaft and operating said screens.
